Hi! Out of curiosity I gave Hudiy 1.2 a shot on a Pi 3B and to my surprise it actually works really well! AndroidAuto runs great over USB and Wifi. Hudiy UI is super smooth as well. Big shout-out to the developers for the optimizations even though the Pi 3B isn't officially supported!
I've put together a short guide in case anyone else wants to run it on a Pi 3B/3B+
a. Wayland doesn't work too well on the Pi 3B (at least mine) so make sure you're running the system on X11
sudo raspi-config
Advanced Options
A7 Wayland
W1 X11
Save settings and reboot
b. Let Hudiy start automatically on X11
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
Add this at the end of the file
/home/pi/.hudiy/share/hudiy_run.sh
c. Use BG bandwidth for hotspot
nano /home/pi/.hudiy/share/config/main_configuration.json
Find "bandwidth" inside "hotspot" and change it to "BG"
Reboot the Pi and voila - Hudiy is autostarted!
In my case RAM usage is about 500MB and CPU stays under 20% most of the time. Hopefully this helps anyone who's stuck with crankshaft or opendash on the Pi 3.
